Description

Technical Field

[0001] The utility model relates to the field of air tightness detection, in particular to an air tightness detection clamping device for a folded angle plug door. Background Art

[0002] The brake device is an important part of railway freight cars. The purpose of the brake device inspection is to restore the performance of the brake device. The angle plug is a control valve that connects and cuts off the air between railway locomotives, locomotives and vehicles, and vehicles and vehicles. After the handle is lifted, it can be rotated 90 degrees to open and close the air path.

[0003] At present, when inspecting the corner plugs of railway freight cars, since the corner plugs are roughly cylindrical in shape and the central axis at both ends has an angle of 60°, the existing technology generally uses a fixed longer horizontal side and manually tightens the other side with a sealing gasket and a plug. This sealing method is greatly affected by human factors and has a poor sealing effect. The process is limited by the state of the person. After the inspection, the accuracy of the installation cannot be effectively guaranteed, which often leads to a large number of loosening and deformation problems when the vehicles are connected. When the angle is too large, the hoses of the two vehicles will be twisted after the connection, reducing the life of the hoses; when the angle is too small, the hoses will pull each other when the train passes through a track with a small turning radius, causing the corner plug to loosen and reducing the life of the hose. The detection method used in the existing technology will cause the two end faces of the corner plug to not fit tightly during the inspection, thereby affecting the air tightness detection effect and causing the accuracy of the installation to be unable to be effectively guaranteed.

[0004] Since the angle plug door is roughly cylindrical as a whole and the central axes at both ends have an angle of 60°, it is generally used to fix the longer horizontal side and manually tighten and seal the other side with a sealing gasket and a plug. This sealing method is greatly affected by human factors and has a poor sealing effect. Another sealing method is urgently needed.

[0005] In order to solve the above problems, the utility model provides a clamping device for detecting air tightness of a folded angle plug door. Utility Model Content
